摘要：

In order to compare the influence of temperature on the micro-explosion intensity and frequency of BD60E40 droplet group (the ratio of biodiesel to ethanol was 60:40) and BD60R10E30 droplet group (the ratio of biodiesel, RP-3, and ethanol was 60:10:30), a five-droplet synchronous heating experimental system was established. Using this experimental system, the heating sequence experiments of BD60E40 droplet group and BD60R10E30 droplet group in the range of 500-800 degrees C were carried out under simulated atmospheric conditions. By adjusting the ambient temperature, not only the ignition and expansion of the droplet group were found, but also the supermicro-explosion phenomenon was observed. In the experiment, the life cycle of droplet group had different characteristics under different temperatures and the life cycle of BD60E40 droplet group was calculated under 500-800 degrees C. The characteristics and reasons of BD60E40 droplet group life cycle changing with temperature were analyzed. Furthermore, the frequency model of supermicro-explosion of droplet group was established and calculated, and the influence of combustion on supermicro-explosion was analyzed. Furthermore, the reason for the difference of micro-explosion intensity between BD60E40 droplet group and BD60R10E30 droplet group was compared and analyzed.
